Support patternProperties?

[jbrok]

Using Schema Guru DDL on a JSON Schema that uses patternProperties in 0.4.0 to create json path files and the .sql fails. The files are created but without my custom data fields from my properties. The JSON schema is created with Schema Guru (and then manually edited patternProperties). Schema DDL throws no error.

The documentation says this is supported:
"Object without properties, but with patternProperties becomes VARCHAR(4096)"

JSON Schema

...
  "type" : "object",
  "patternProperties" : {
    "^results(List)?$" : {
      "type" : "object",
      "properties" : {
        "subLocations" : {
...

Command
$ ./schema-guru-0.4.0 ddl --with-json-paths ./schemas/

Result
Missing data.fields.

    "ref_parent"     VARCHAR(255)  ENCODE RUNLENGTH NOT NULL,
    FOREIGN KEY (root_id) REFERENCES atomic.events(event_id)
)

When I change patternProperties back to properties in the JSON and regenerate the files, it's working as expected..

Thanks @jbrok. Seems like a bug. I'll investigate it.
